@BulldogLowell this has been quite a project to watch unfold and develop into just the greatest project. I am learning more just following you programing wizards, than I learn surfing . Thanks for the project and the inside tracks on programming etc.
I have got my tripping gage back from my local 3d hub shop and the job looks good I hope to have it running hardware and soft before I return to and take it to Florida this fall.

@nostradamux I had one printed using @BulldogLowell design and thru 3Dhubs.com the build was good and I used abs also for material. My cost in USA was approx. $17 usd and took a day to print and receive, looks good.
However I have not gotten far with project due to other issues unrealated just with I had more time and experience.
